DRAFT AND BUFFING APPARATUS.

Patented Mar. 25, 1913.

Divided and this application filed September 24, 1908. Serial No.454,597.

To all whom it may concern:

Be it known that I, HENRY F. Porn, a citizen of the United States, and aresident of Cleveland, Guyahoga county, Ohio, have invented a new anduseful Improvement in Draft and Bufling Apparatus, of which thefollowing is a specification, reference being had to the accompanyingdrawings, in which Figure 1 is a sectional elevation, partly brokenaway, showing a preferred form of my draft and bufiing apparatus; Fig. 2is a partial plan view; Fig. 3 is a side elevation of the parts shown inFig. 2; Figs. 4 and 5 are cross-sections on the lines IV IV and VVrespectively of Fig. 3; Figs. 6 and 7 are views similar to Figs. 2 and3, showing a modified construction; Figs. 8 and 9 are cross-sections onthe lines VIIIVIII and IXIX respectively of Fig. 7; Figs. 10 and 11 areviews similar to Figs. 6 and 7, but showing a further modification; andFig. 12 is a section on the line XII-XII of Fig. 11.

In the drawings, 1 is the coupler head having a shank 2 affixed to arear extension 3, which extends rigidly from the coupler to its rearpivoted connection with the draft rigging 4, the draft rigging beingmounted between the car sills so as to be adapted for longitudinalmotion in bufiing and draft, but being held from lateral swinging motionwith the coupler.

6 is the transverse member of the butter, having a shank 7 which isdivided or forked longitudinally and is attached by vertical bolts 8 toa buffer shank filler block extension 12.

10 is the end sill of the platform, which acts as a carry iron for thebuffer, passing for this purpose between the arms of its shank 7, beingcurved or segmental in form so as to present a forward curved buffingface for the transverse member 6 of the buifer when it reaches the rearlimit of its buffing motion.

The coupler-shank extension 3 has aforwardly extending shoulder on whichthere is a barrel-shaped spring casing 3 into which the buffing spring11 is inserted.

A filler block 12 is placed between the rear ends of the divided buffershank 7 so as to fill the space between the same, and this filler blockhas at its end lateral wings 12 which fit against the sides of thespring casing 3 and slide thereon in the forward and backward motion ofthe buffer. The buffer is retained in place by a tail bolt 13, which isattached within a recess 14 in the filler block 12 by means of the bolts8, by which the filler block is fastened to the buffer shank. This tailbolt has at its rear end a slot 16 for the insertion of a key 17 whichabuts against the rear wall of the spring casing and holds the tail boltfrom forward movement. This tail bolt and key enables the buffer springto be initially compressed in the spring casing. The rearward motion ofthe tail bolt is provided for by forming a slot 18 in the web of thecoupler shank extension.

In the modification shown in Figs. 6 to 9, the buffer springs 11 areplaced in a barrelshaped casing 3 formed on a shoulder on the couplershank extension 3, but the buffer shank is guided and held betweenvertical plates 19 which extend upwardly from the coupler shankextension, thus rendering unnecessary the use of the wings 12 on thefiller block 12 described with reference to the other figures of thedrawings. The buffer filler block 12 in this case is formed at its rearend with a spring seat and thimble 12 which abuts against and holds thespring 11, and shoulders at the rear end of the filler-block 12 abutagainst the rear of the plates 19 and prevent forward withdrawal of thebuffer. In this case the function of the spring 11 is to press thebuffer forwardly against the opposing buffer of another car, and forthis reason its resisting capacity need not be great. The buflingstresses are communicated from the rear end of the buffer to the couplershank extension 3, when the buffer spring 11 is fully compressed.

In the modification shown in Figs. 10, 11 and 12, the plates 19 arereplaced by upwardly projecting integral shoulders 19 which extends fromthe coupling shank extension 2. In this form of the invention I omit thespring casing and employ instead thereof a thimble 3 which supports theend of the spring 11 The buffer spring shown in this case is theordinary double coil spring, substituted for the lighter spring 11 abovedescribed.

In Fig. 1, I have shown the buffer as having a depending stirrup orcarry-iron through which the coupler shank 2 extends.

This stirrup of carry-iron not only forms a support for the coupler andits shank but it provides means for causing the buffer and coupler toswing laterally in unison.

Within the scope of my invention as described in the claims,modifications may be made by those skilled in the art, since lVhat Iclaim is 1. A radially swinging pivoted coupler and coupler shankextension, a draft rigging to which said extension is pivoted, a buffermounted for longitudinal movement, and a buffer spring interposedbetween the buffer and the main body of the coupler shank extension andseating upon said main body at its rear end, that portion of the body ofthe coupler shank extension which lies between the buffer spring and thedraft rigging being in longitudinal alinement with said spring andrigging; substantially as described.

2. A radially swinging pivoted coupler and coupler shank extension, adraft rigging to which said extension is pivoted, a buffer mounted forlongitudinal. movement, and a buffer spring interposed between thebuffer and the main body of the coupler shank extension and seating uponsaid main body at its rear end, said main body having a pocket thereinto receive said spring, that portion of the body of the coupler shankextension which lies between the buffer spring and the draft riggingbeing in longitudinal alinement with said spring and rigging;substantially as described.

3. A radially swinging pivoted coupler and coupler shank extension, adraft rigging to which said extension is pivoted, a buffer .mounted forlongitudinal movement, and a buffer spring interposed between the bufierand the main body of the coupler shank extension and seating upon saidmain body at its rear end, that portion of the body of the coupler shankextension which lies between the buffer spring and the draft riggingbeing in longitudinal alinement with said spring and rigging, and itsforward portion being offset downwardly, the buffer spring extendingback as far, at least, as the ofiset in said extension; substantially asdescribed.

4:. A radially swinging pivoted coupler and coupler shank extension, adraft rigging to which said shank extension is pivoted, a buffer mountedfor longitudinal movement, and a buffer spring interposed between thecoupler shank extension and the buffer, that portion of the couplershank extension which lies between the buffer spring and the draftrigging being in longitudinal alinement with said spring and rigging,and the buffer having a tail bolt extending rearwardly into engagementwith the last named portion of said extension; substantially asdescribed.

5.
